The SPL Model 2049 Kultube Stereo Compressor is a versatile compressor with a broad range of control facilities that cover many typical compressor applications. From improved stereo mixes in the "MIDI Studio" to surround mastering with several devices connected, all jobs can be undertaken with a high degree of sound quality.
The Kultube user has a range of compression tools always available, from subtle unobtrusive compression to very obvious 'effect' compressions. Used conventionally or as an effect, in professional recording or mastering applications, the Kultube is designed to improved audio quality with musicality and user-friendliness.
Applications cover those of a classic compressor for vocals and instruments, in both mono and stereo, through stereo operation for subgroup processing to stereo mastering and multichannel/surround projects.
The optional 24-bit / 192 kHz AD Converter Module 1090 can be inserted in the Kultube for digital compression processing.
The Kultube awaits you to control the future of sound.
